LED Arrow Board designed with compact structure bright red LED arrow and durable aluminum plate body for clear road warning

The front is centered on a large red LED arrow, with a clear and intuitive direction that is identifiable from a distance. Red naturally carries warning associations in road scenarios, and combined with high-brightness LED illumination, it creates a strong visual guidance effect.

Formed from one-piece bent aluminum plate, the body features clean, flowing lines with no obvious seams and a strong sense of unity. The aluminum surface undergoes anti-rust electrostatic spraying, presenting a uniform, fine matte texture that combines the professional feel of industrial equipment with weather resistance.

The overall form is compact and structurally orderly, occupying minimal space. With a portable handle, one person can carry it easily; it can be stored flat or upright for convenient vehicle loading and warehouse management.

The body is equipped with a portable handle that blends naturally with the overall design without appearing obtrusive. The handle position is carefully considered so that the center of gravity stays balanced during one-handed carrying, making transport effortless.

The structural designs for four installation methods — wall-mounted, hanging, independent placement, and vehicle-mounted — are simple and do not disrupt the overall appearance. Once installed, the body remains clean and tidy without looking cluttered.

Aluminum alloy plate is used as the main material. Aluminum has low density and high strength, keeping the total weight at 3KG while ensuring structural rigidity, allowing one person to carry and move it. Compared with the heaviness of iron warning signs and the fragility of plastic materials, aluminum alloy strikes a balance between lightness, strength, and durability.

The entire aluminum plate is formed through one-piece bending rather than multi-piece splicing and welding. This reduces seams and welding weak points, providing high overall strength and strong deformation resistance. Whether during transport vibration, on-site impacts, or long-term outdoor use, the body is less likely to loosen, crack, or deform.

The aluminum plate surface undergoes anti-rust electrostatic spraying, forming a uniform and dense protective layer that effectively resists moisture, salt spray, and UV erosion. It is rust-proof, waterproof, and fog-resistant, and won't easily fade, peel, or rust during long-term outdoor use, adapting to harsh weather such as rain, snow, and fog.

The aluminum shell forms the first line of defense, blocking rain, snow, and direct water contact. The core circuits and battery box are independently sealed, forming the second line of defense to prevent moisture and dust from intruding into critical components. Together, the double protection enables stable operation across a wide temperature range of -20℃~+60℃.

Sturdy aluminum structure, weather-resistant coating, and sealed circuits — the combination allows the product to undertake long-term outdoor warning tasks without frequent replacement or maintenance, reducing usage costs.
